Background

The wire mesh demister is an efficient gas-liquid separation device, is widely used in refrigeration, chemical industry, petroleum and other industries, and has the working principle that: when the mist-laden gas rises through the mesh at a certain speed, the mist collides with the mesh filaments and is attached to the filament surfaces due to the inertia of the rising mist. The dispersion of the mist on the surface of the filament and the gravity sedimentation of the mist enable the mist to form larger liquid drops and flow to the junction of the two filaments along the filament.
